在尝试运行后出现的错误下方，如果回滚顶级 Tensorflow 2.0 版本，该错误不会持续存在。在 Jupyter Notebook 中自动完成时，所有部分都正常显示，只是无法加载。有什么可能的解决方法来避免回滚到旧版本？

在：

from tensorflow.keras.models import Sequential

出去：

你可以在 TensorFlow Keras 中做这些顺序模型的例子。你也可以根据你的情况添加层。


from tensorflow import keras
from tensorflow.keras import layers
from tensorflow.keras import Sequential

model = Sequential()
# Adds a densely-connected layer with 64 units to the model:
model.add(layers.Dense(64, activation='relu'))
# Add another:
model.add(layers.Dense(64, activation='relu'))
# Add an output layer with 10 output units:
model.add(layers.Dense(10))

或者

import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import layers

model = tf.keras.Sequential()
# Adds a densely-connected layer with 64 units to the model:
model.add(layers.Dense(64, activation='relu'))
# Add another:
model.add(layers.Dense(64, activation='relu'))
# Add an output layer with 10 output units:
model.add(layers.Dense(10))

从最新的 TensorFlow 版本 >= 2.2.0 开始，开发人员已经修改了加载模型/层等的方式（使其更容易）。

因此，Sequential 类不再在包tensorflow.keras.models中而是在tensorflow.keras

只需使用：

from tensorflow.keras import Sequential

它会正常工作。
干杯
